What is SAP?
SAP is recognized as an ERP software practiced for integrating and automating complex business processes such as production planning, human resources management, inventory management, customer service, distribution, finances or logistics. SAP architecture is classified into three layers or servers. There is the presentation layer, the application layer, and the database layer. Each of them is capable of specific processes and presents to the good functioning of the whole system. They all work on separate servers unlike the two layer architecture, where the presentation layer and the application one were on the same server and the database layer was maintained independently. Though, the three layers architecture is usually utilized in production and in complex systems. We can even talk about one level SAP architecture, in which all data is stored on a single server.
SAP R/3 Architecture
When the client-server technology turned famous between the ERP developers SAP released its SAP R/3, in which, R means for real-time data processing and 3 means three-tier architecture. Because of adoption of this technology that version of SAP ERP was compatible with versatile platforms and operating systems. The newest version of SAP ERP is SAP ECC 6.0 that is a replacement of R/3 architecture.
SAP has the business precise 3-Layer Architecture and which is known as R/3 Architecture.It comprises of three 3 Layers:
1. Presentation Server/ Layer
2. Application Server/ Layer
3. Database Server/ Layer
1. Presentation Server/ Layer:
It is a customer for every SAP Solutions. It is also known as SAPGUI. There are 3 types of SAP GUI
1. SAP GUI for windows- Used on Windows OS
2. SAP GUI for JAVA- Used on all OS where JAVA is supported
3. SAP GUI for HTML- Used for web based
SAP gave various versions of GUI (4.6c, 620, 640, 700, 710)
2. Application Server/ Layer:
It handles the client request and processes them to the database. It contains dispatcher to process and control the client request, interpret the requests and , work process to process, Buffer areas to cache the regularly accessed data. It consumes the pressure both from Client and the server.
3. Database Server/ Layer/:
It is the region where the complete data remains. It has its own queue, process, buffers, and request handling device. Maximum databases are on Oracle. SAP is launching MAXDB (without any license key), Microsoft SQL Server & IBM DB2 with reduced charges.SAP is concentrating SMB (Small Mid-sized Business) and developing SAP for almost 1 million/ Rs. 10 Lakhs/ per client.
Benefits SAP R/3 Architecture
SAP R/3 architecture depends on its three layers which are an application server, database server and presentation server, the application server is the third layer that was added to the former two-tier architecture to make it three-tier architecture. The presentation server of SAP R/3 acts as GUI and is an application known as sapgui.exe. This application is placed on the client system which accepts the input and forwards it to the application server that processes the requests and returns back the results or the output of the input.
The advantage of this architecture, aside from a number of users and speed, was the integration of other modules with key and frequently used modules. The principal modules of the organization were at the one place while all the actions within those modules could be viewed in other related modules in real time. This also immensely increased the production of recording and analytical tools and management of various departments working at diverse places. Large companies could install this ERP which would operate as an autonomous application for the group and could also give the consolidated view of the whole industry at the highest level in real time.
The cross application functionality and enterprise-critical shared IT system supports in maintaining business workflows even at the divisional level what makes application remarkably user-friendly. It presents simple and comprehensive integration with other successful non-SAP products. It can comply with various levels of IT infrastructure in contradiction with SAP R/2 architecture that handled to run on mainframe systems.
